15 Claims. (Cl. 13)

This invention relates to pull out chair or sofa beds.

An object of this invention is to improve the device shown in our co-pending application, Ser. No. 174,380 filed July 18, 1950 for Chair or Sofa Beds, now Patent No. 2,642,583 issued June 23, 1953.

' Another object of this invention is to provide a device of the character described, having a bed frame comprising a plurality of interpivoted sections and which may be collapsed into a sofa or chair frame or pulled out to provide a bed, said device being provided with highly improved means for locking the sections against movement other than in a predetermined progressive relationship during the major portion of the movement of said sections to aid in compressing the mattress which folds within the folded sections, and to prevent accidental opening up of said sections in any other than in a predetermined manner.

In prior pull out beds or sofa beds, there is usually provided a bed frame comprising a head section pivoted to the sofa, an intermediate section pivoted to the head section, a short fold section pivoted to the intermediate section, and a tail or foot section pivoted to the short fold section. When the bed frame is collapsed the head section is usually in a vertical position at the rear of the sofa frame, the intermediate section is in a horizontal position at the bottom of the sofa frame, extending forwardly from the head section, the short fold section is pivoted to the front end of the intermediate section, andextends upwardly therefrom, and the tail or foot section is pivoted to the upper end of the short fold section and extends rearwardly therefrom in parallel relationship above the intermediate section. In such prior constructions when it is desired to unfold the bed frame, the short fold section which is located near the front of the sofa frame is usually grasped, pulled somewhat upwardly and then forwardly, so that the frame swings somewhat forwardly of the sofa. During such action, the tail section does not open up. Then the operator must grasp the tail or foot section and swing it upwardly and forwardly to completely unfold the bed frame. Thus the unfolding of the'bed requires two distinct operations, and the first operation which is the pulling of the frame forwardly over the front bottom'board of the sofa, does not act to swing the tail or foot section forwardly and upwardly or unfold such portion of the bed frame.

It is therefore an object of the present invention to provide a highly improved bed frame wherein the movement of all four sections of the frame are integrated and have a predetermined relationship, the arrangement being such that when the short fold section of a collapsed or folded bed frame is pulled forwardly and upwardly, the tail or foot section will automatically swing upwardly and forwardly or in an unfolding direction so that continued movement will unfold the entire bed.

7 Still another object of this invention is to provide a device of the character described including a foot section which will swing upwardly and forwardly as an intermediate portion as the device is pulled forwardly.

Still a further object of this invention is to provide in a pull out bed of the character described, a bed frame comprising a plurality of interconnected sections so constructed that the movement of any one section affects the movement of all the remaining sections.

A still further object of this invention is to provide in a collapsible bed frame of the character described, means to prevent opening up of the tail section from the folded position, without unfolding the remaining sections, during a major portion of the unfolding operation.

Yet another object of this invention is to provide a pull out or sofa bed of the character described, which shall be relatively inexpensive to manufacture, safe in use, which shall be sure and positive in operation, easy to handle, and which shall yet be practical and efiicient to a high degree.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts, which will be exemplified in the construction hereinafter described, and of which the scope of invention will be indicated in the following claims.

Referring now in detail to the drawings, 16 designates a pull out sofa or chair bed. The same comprises a sofa or chair frame 11 which may be of usual construction and comprises generally a back wall 12, side walls 13, front bottom board 15, and arm boards 16. Rearwardly of the arm boards 16 is a transverse brace board 17 to which may be attached an upholstered portion 18 which forms the back of the sofa or chair. The sofa or chair frame may be upholstered in any suitable fashion.

Attached to the inner sides of the side walls 13 in spaced relation to the back wall 12 are a pair of vertical metal supports 20. Each comprises vertical portion 21 contacting the inner surface of side wall 13 and an inwardly oifset portion 22 extending from the lower end thereof and formed with a foot 23 which may contact the floor. Extending inwardly from the upper end of portion 21 is portion 24 formed with upstanding finger 25. i It will be understood throughout this application that the structure of the entire pull out sofa or chair bed is symmetrical about its mid-section so that only one side of the structure is shown, it being understood that the opposite side is similar and symmetrical to the parts shown.

Members 20 may be attached to the side walls 13 in any suitable manner such as by screws, bolts or otherwise. Attached to the upper ends of the offset portions 22 as by rivets 26 are rear ends of horizontal support members 27 which may also be attached to the side walls 13 by additional screws, rivets or other fastening members 28. Members 2'7 extend horizontally toward the inner sides of the front boards 15. Adjacent the board 15, members 27 are formed with inwardly extending U shaped portions 29 from which forwardly extend fingers 3t) somewhat spaced from the side walls 13. The rear ends of members 27 are disposed between the offset portions 22 of members 26 and the side boards 13.

Attached to the inner sides of the front boards are transverse horizontal straps 31 formed at their outer ends with offset fingers 32 contacting the inner surfaces of the side walls 13 and riveted to the fingers 30 by rivets 33.

Interconnecting members 27 and on each side of the bed are upwardly and rearwardly inclined brace members 35 formed at their under edges with a plurality of spaced notches 36 for the purpose hereinafter appearing.

Pivoted to the upper ends of members 20 and disposed therebetween, is a head section 46 of a collapsible bed frame F. The head section 40 comprises a pair of members 41 each comprising a portion 42 and a portion 43 at right angles thereto. Members 41, 42 may be made of angle iron, each comprising a flange in a vertical plane and flanges at right angles to the first flange. The pivotal connection is by means of rivets 44. It will be noted that portions 42 are horizontal and extend rearwardly from the rivets 44 when the bed frame F is fully collapsed as in Fig. 4; and in such position the portions 43 extend vertically downwardly. When the bed frame F is fully pulled out, member is rotated in a counterclockwise direction from Fig. 4 through a total angle of 90 to bring portions 42 to a position where they extend downwardly from the rivets 44, and in such position the portions 43 extend horizontally in a forward direction as shown in Fig. 1. Portions 42 are interconnected by transverse horizontal brace members 46 (see Fig. 2).

Pivoted to the forward end of the head section 40 is an intermediate section 47. Said intermediate section 47 comprises side links 48 riveted as by rivets 49 to the forward ends of portions 43. The links 48 extend in horizontal directions when the bed frame F is fully pulled out, as shown in Figs. 1 and 2. Pivoted to the forward ends of the intermediate section 47 is a short fold section 58, and pivoted to the short fold section 50 is a tail or foot section 51. The short fold section 50 comprises links 52 pivoted at their rear ends to the forward ends of the links 48 by means of rivets 53. The tail or foot section 51 comprises side links pivoted at their rear ends to the forward ends of the links 52 as by rivets 56. Pivoted to the rivets 53 are intermediate legs 57. Pivoted to the links 55, rearwardly of their front ends, as by rivets 58, are front legs 59. The forward ends of the links 55 are interconnected by cross brace 60. Attached to the front ends of the links 55 are short vertical side posts 61 extending above and below said links. Pivoted to the upper ends of the posts 61 as by rivets 62 are foo-t boards 63 interconnected by coil tension springs 64 to the lower ends of the post 61 and normally maintained in a position shown in Fig. 1 by said springs 64. The foot board 63 may be swung, however, in a counterclockwise direction, looking at Fig. 1, about the rivets 62 toward the top of the tail or foot section 55 so as to clamp the foot end of a mattress placed at the top of a bed frame thereto.

The side portions 43 and links 48, 52 and 55 all have lower inwardly extending horizontal flanges which are interconnected and are also connected to the cross braces 46 and by any suitable bed platform or bed spring 65 made of crossing interconnecting wires or any other suitable construction. The cross wiring 65 may be interconnected by coil springs 65a. to said horizontal flanges. The links 52 are each formed with a horizontal slot 66 adjacent its forward end, for the purpose hereinafter appearing.

Pivoted to intermediate portions of the side links 48 as by rivets 67 are bell cranks 68. Each bell crank 68 comprises a link portion 69 pivoted at its upper end to the rivet 67 and its lower end by rivet 70 to the U- shaped offset portion of member 27.

The arms 69 have intermediate dog leg bends as shown in Fig. 1 of the drawing and comprises an upper inclined portion 72 inclined downwardly and rearwardly from the rivet 67 and a second portion 73 inclined downwardly and rearwardly from the rear end of portion 72 but at a greater inclination to a horizontal plane.

Attached to the lower end of arm 69 and inclined upwardly and rearwardly therefrom is an arm 74. Arm 74 may be welded or otherwise fixed to the lower end of portion 73. The upper end of each arm 74 is formed with an opening 75. Interconnecting the opening 75 with one of the notches 36 of brace 35 is a coil tension spring 76, for the purpose hereinafter appearing.

Pivoted to portions 43 of members 40 rearwardly of their forward ends as by rivets 77, are links 78 normally inclined slightly upwardly when the bed frame is pulled out. Pivoted to the links 48 as by rivets 79 disposed rearwardly of the rivets 67 are bell cranks 80 each comprising an upwardly and rearwardly inclined arm 81 and a downwardly and rearwardly inclined arm 82 formed with a slot 82a. The upper end of arm 81 is pivoted as by rivet 83 to the forward end of link 78. Link 85 carries rivet 84 passing through slot 82a in arm 82. The forward end of link 85 is pivoted as by rivet 86 to leg 57 somewhat below the rivet 53. The link 85 may be of a wide V shape having a slight leg bend at an intermediate portion thereof. It will be noted that the legs 57 on opposite sides of the bed are interconnected by cross braces 88.

The links 48 are formed with longitudinal slots 90 about twice as long as slots 66 and disposed rearwardly of the rivets 79. Pivoted to the rivets 84 are links 91 inclined upwardly and rearwardly when the bed frame is in the position shown in Fig. 1. Carried by the upper ends of links 91 are rivets 92 passing through the slots 90 from the outer to the inner sides of the vertical flanges of links 48.

Pivoted to the rivets 92 are the rear ends of push levers 93 disposed at the innerisides of the vertical flanges of links 48. Each push lever 93 runs along the inner side of the vertical flange of link 48, horizontally therewith when the bed frame is fully pulled out.

At the forward end of each push lever 93 is a transverse rivet 94 passing through slot 66.

Pivoted to each link 55 forwardly of the pivot 66 is rivet 100. Pivoted to each rivet 100 is a link 101 extending downwardly therefrom, when the bed frame is fully pulled out. Pivoted to each rivet 56 is a link 102 also extending straight down when the bed frame is fully pulled out. The links 101 are of greater length than the links 102. They are interconnected by links 103 pivoted thereto by rivets 102a and 103a. The links 103 are inclined rearwardly and upwardly when the bed frame is fully pulled out. Attached to said links 103 is a transverse board 104 which is adapted to rest on the top edge of the sofa board when the bed frame is fully collapsed as will hereinafter appear.

Links 101 are interconnected to front legs 59 by links 105 through rivets 106 and 107. The links 105 have an intermediate shallow leg bend as shown in Fig. 1. Pivoted to an intermediate portionof each link 102 as by rivet 108 is a link 109 inclined upwardly and rearwardly when the bed frame is fully pulled out. The upperends of the links 109 are connected to the rivets 94 which slide in the slot 66. The rivets 94 and 100 are interconnected by links 110 disposed at the inner sides of the vertical flanges of links 52 and 55. The links 110 each comprise a vertical wall flange 111 from the upper end of which extends upwardly a horizontal flange 112 whichoverlies the upper edges of the vertical flanges of links 52 and 55.

Attached to the vertical flange portions of the links 52 above the slots 66 as by screws 113 orother fastening means are stud members or lugs 114, the purpose of which will be explained hereinafter.

Attached to the lower ends of the post 61 are stop lugs 61a extending downwardly therefrom (Figs. 1 and Attached to the inner sides of the vertical portions 21 of members are brackets 115 having inwardly extending portions adapted to be contacted by stop lugs 61a when the bed frame is in fully folded condition.

It is understood that a mattress may be placed on the pull out bed and is supported by the wires 65. The mattress clamp63 may then be swung downwardly in a counterclockwise direction, looking at Fig. 1 to clamp the foot end of the mattress. To collapse the bed from its fully pulled out position shown in Figs. 1 and 2, the foot of the bed may be grasped and pulled upwardly and rearwardly to cause the foot or tail section 51 to swing about the pivots 56 in a counterclockwise direction, looking at Fig. 1 through an angle of 90'. Such action will causelegs 59 to swing in a clockwise direction relative to section 51 about the pivots 58 toward members 55. Such movement will cause links 105 to swing arms 101 about the pivots 100 in a clockwise direction relative to members 55 into theplane of said members. Arms 102 will also swing in a clockwise direction looking at Fig. 1, about the pivots 56. Such movement of arms 102 will cause links 109 to move in the direction for pushing the pivot pins 94 to the left (looking at Fig. 1) in slots 66. The movements of the pivot pins 94 to the left cause a pushing movement of the pushing levers 93 to the left, thereby causing the pivot pins 92 to slide to the left in the slots 90.

Such movement will cause rivets 84 to slide upwardly in the slots 82a of arms 82. During such movement the pivot point 100 swings upwardly in an are thereby raising the links 110. During such movement the members 52 remain in horizontal as shown in Fig. 6. The push bars 93 also remain in horizontal position until the pivot pins 94 reach the rear ends of slots 66. At this time members 55 are at right angles to members 52.

When the rivets 94 strike the ends of slots 66 further upward movement of tail member 51 will cause swinging of links 52 about pivots 53 in a counterclockwise direction, looking at Fig. 1. At the same time the push bars 93 are swung in a counterclockwise direction about the pivots 92 and said pivots continue moving to the left in slots 90, looking at Fig. 1, thereby causing rotation of the bell crank about the pivots 79 in a clockwise direction. Such action causes the links 78 to pull on rivets 77 in an upwardly inclined direction causing a break at the joints 49. Such action causes members 40 to swing in a clockwise direction about the pivots 44. Such action also causes links to pull the legs 57 upwardly toward members 48. This action is aided by the spring 76 which pulls against the bell crank 68. The bed is thus collapsed through position of Fig. 7 to the position of Figs. 3 and 8.

It will be noted that when the tail section 51 passes the upright position during the collapsing action of the bed, the pins 114 contact the upper edges of the push bars 93 so as to prevent section 51 from being swung upwardly about the pivot pins 56 without again unfolding the bed. In other words, once the tail member 51 passes the upright position in a counterclockwise direction, looking at Fig. 1, it cannot be moved relative to members 52 without also swinging members 52 back toward horizontal unfolded position. Thus the pins 114 serve as a lock for the tail section to retain the folded mattress tightly between sections 51 and the intermediate section 47. Further movement of the tail section be yond upright position when collapsing, or toward upright position when unfolding, must be accompanied by movement of all the sections in predetermined relation.

As the bed continues in its collapsing move from the position of Fig. 3 to the fully collapsed position of Fig. 4, portions 43 of section 40 move into vertical position, members 48 move into horizontal position, and members 59 move into horizontal position spaced above members 48 and members 52 move to vertical position. During such movement, the springs 76 are tensioned to act as counterbalances for aiding in the opening or unfolding movement of the bed frame.

It will be noted that during the collapsing of movement of the bed frame, the tail section 51 and the intermediate section 47 first move to a downwardly and rearwardly inclined position of Fig. 3, and the short fold section 50 moves to upwardly and rearwardly inclined position, so as to straddle or move over the top of the front board 15. As the bed swings from the position of Fig. 3 to Fig. 4, section 50 moves back to vertical position whereas sections 51 and 47 move back to horizontal positions so as to catch the bed frame between the front board 15 and the back wall 12. The board 104 moves into contact with the top edge of the front board 15 so as to be in vertical alignment therewith so as to rest thereon.

It will be noted that the entire collapsing movement of the bed may be carried out With one pushing movement. After the tail section reaches the vertical upright position during the collapsing movement, further movement of the bed frame causes correlated movements of all four sections, and no section can be moved without movement of the other sections.

Y During the unfolding movement, the board 1114 may be grasped and pulled upwardly and forwardly and again all four sections move in predetermined correlation with each other until the tail section 51 is in vertical upright position and the legs 57 touch the floor. Thereafter continued movement of the tail section will swing it down to horizontal position with the legs 57 touching the fioor.

In Figs. 18 to 26 there is shown a pull out bed a embodying the invention and illustrating a modified construction. The bed 10a comprises a sofa or chair bed frame 11 similar to the one described in connection with the bed 10. Attached to the side walls 13 of the frame 11 are members 21) similar to the members 21? described above. Also attached to the side walls are members 27 and members 31 similar to members 27, 31 described above.

At the upper ends of members 29 are the pivots 44 to which is pivoted a bed frame F illustrating a modified construction. The frame F comprises head sections pivoted to the pivots 44. Pivoted thereto is the intermediate section 47 comprising links 48, all as described hereinabove, and formed with slots 91). Pivoted to members 48 are the bell cranks having upwardly and rearwardly inclined arms connected by links 78 to portions 43 and members 40 by means of pivots 77.

Similarly to the frame F, bell cranks 89 have downwardly extending arms 82 formed with slots 82a through which extend a pivot pin 84 at the lower end of link 91, at the upper end of which is a pin or pivot 92 carried by the rear end of the push lever 93.

Pivoted to the members 48 as by pivots 67 are the bell cranks 63 connected by springs 76 to the inclined cross braces 35. In the frame F, however, the legs 57 and the links of frame F are omitted. Members 48 are connected by pivots 53 to the links 52a of the short fold section 5110. The links 52a are connected by pivots 56a to links 55a of a tail section 51a. The links 52a are formed with longitudinal slots 66a similar to the slots 66.

Extending downwardly from the links 52a, adjacent the pivots 56a are ears to which are pivoted as by pivots 131 the upper ends of legs 132. Welded to the legs 132 are upwardly and rearwardly inclined brace members 133, the upper ends of which are connected by pivots 134 to links 135 normally in the horizontal position when the bed is unfolded. The rear ends of the links 135 are connected by pivot pins 136 to links 48 at points rearwardly of the pivots 53. The side members 55a of the tail section 51a are of dog leg shape, each having a rear horizontal portion 137, a front horizontal portion 138 at a level higher than the portion 137 and an intermediate forwardly and upwardly inclined portion 139. Pivoted to the links 55a between the portions 137 and 139 as by pivot pins 141) are the upper ends of links 141.

It will be noted that the cross brace 133 extends downwardly and to the right of the leg 132. interconnecting the lower end of the cross members 133 with the lower end of the link 141 is a link 142. Link 142 is connected to the cross brace 133 and link 141 by means of pivot pins 143 and 144. Attached to the links 142 is a front board 104a similar to the front board 1114 of Fig. 1.

Pivoted to the links 55a adjacent the forward ends thereof as by pivot pins 146 are the upper ends of legs 147. Intermediate portions of the links 141 are connected to the links 147 by means of links 148 also of dog leg shape.

Fixed to the front ends of links 55a are members 61 to each of which is pivoted member 63 interconnected to member 61 by spring 64. The lower ends of memher 61 also carry stop pins 61a, all similar to the construction of Fig. 1.

Pivoted to the pivot pins are front ends of links 110a similar to the links 110 of Fig. 1. The rear ends of the links 110a are connected by pivot pins 94 to the front ends of the push rods 93. Integrally formed with the links 52a are flanges 151) overlying the upper edge of the push bars 93.

Extending downwardly from the one end of each flange 150 is a lug 151 also integral with the inner side of each link 52a. The folding and unfolding operations of frame F are somewhat similar to the folding and unfolding movements of the frame F. As the tail section 51a is swung upwardly, legs 147 are swung toward said tail section. At the same time links 148 swing the links 141 in a clockwise direction thereby causing legs 132 to fold about the pivots 131 toward links 52a.

As section 51a moves up to vertical position, the push bars 93 are pushed to the left (looking at Fig. 18) thereby causing the pivot pins 94 to move to the left in slots 66a. During such movement the links 110a swing in a counterclockwise direction about pivot pins 94. The links 52a remain in horizontal position until after the tail section 51a passes the vertical position, at which time links 52a start swinging upwardly, thereby permitting the push rods to swing about pivot pins 92 as said pivot pins continue moving to the left, the entire bed being collapsed in the manner described hereinabove.

After the tail section 51a passes the vertical position, one end of the flange 150 serves as a stop contacting the push rod 93 to prevent the tail section from being swung upwardly without swinging the section 50a back towards horizontal position. Except as described herein, the folding and unfolding of the bed is similar to the operation which is applicable to Fig. 1.

In Figs. 27 to 30 there is shown a bed frame F" similar to the bed frame F with the exception that the flange 150 of the lug 151 are omitted. Instead, the slots 66b which correspond to the slots 66a and 66, have upwardly and rearwardly inclined offset portions 160, into which the pivot pins 94 move to serve as a lock for the tail section, as illustrated in Fig. 30.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.

8. The combination of claim 1, the slot in said intermediate section being longer than the slot in said short fold section.

9. The combination of claim 1, in combination with a tail section leg pivoted to the tail section and extending downwardly therefrom, a leg pivoted to the short fold section and extending downwardly therefrom, a link fixed to the short fold leg, an intermediate link pivoted to the tail section and extending downwardly therefrom, a link interconnecting the tail section leg with the intermediate link, a link interconnecting the upper end of the link which is fixed to the short fold leg with the intermediate section, and a board interpivoted to the lower ends of the link which is fixed to the short fold leg and to the intermediate link.

10. In a pull out bed, a support, a head section comprising a vertical portion pivoted at its upper end to the support and a horizontal portion extending forwardly from the lower end of the vertical portion, a horizontal intermediate section pivoted at its rear end to the front end of the horizontal arm of the head section, link means pivotally mounting said intermediate section to said support, a horizontal short fold section pivoted at its rear end to the front end of the intermediate section, and a tail section pivoted at its rear end to the front end of the short fold section, said intermediate section being formed with a longitudinal slot, said short fold section being formed with a longitudinal slot, a pusher bar, a pin at the rear end of the pusher bar slidably engaged with the slot in the intermediate section, a pin at the front end of the pusher bar slidably engaging in the slot in the short fold section, a link pivoted to the last pin at one end and being pivoted at its other end to an intermediate portion of the tail section, a bell crank pivoted to the intermediate section forwardly of the rear end of the pusher bar, said bell crank having one arm inclined upwardly and rearwardly and connected by a link to the horizontal arm of the head section, said bell crank having a downwardly and rearwardly inclined arm connected by a link to the pin at the rear end of the pusher bar.

11. In' a pull out bed, a support, a head section comprising a vertical portion pivoted at its upper end to the support and a horizontal portion extending forwardly from the lower end of the vertical portion, a horizontal intermediate section pivoted at its rear end to the front end of the horizontal arm of the head section, link means pivotally mounting said intermediate section to said support, a horizontal short fold section pivoted at its rear end to the front end of the intermediate section, and a tail section pivoted at its rear end to the front end of the short fold section, said intermediate section being formed with a longitudinal slot, said short fold section being formed with a longitudinal slot, a pusher bar, a pin at the rear end of the pusher bar slidably engaged with the slot in the intermediate section, a pin at the front end of the pusher bar slidably engaging in the slot in the short fold section, a link pivoted to the last pin at one end and being pivoted at its other end to an intermediate portion of the tail section, a bell crank pivoted to the intermediate section forwardly of the rear end of the pusher bar, said bell crank having one arm inclined upwardly and rearwardly and connected by a link to the horizontal arm of the head section, said bell crank having a downwardly and rearwardly inclined arm connected by a link to the pin at the rear end of the pusher bar, the connection between the upwardly inclined arm of the bell crank and the link which connects said arm with the pin at the rear end of the pusher bar comprising a pin and slot connection.

12. The combination of claim 11, the slot in the intermediate section being longer than the slot in the short fold section, and the pins on said pusher bar being located at the forward ends of said slots when said horizontal arm of the head section and said intermediate short fold and tail sections are in horizontal positions and the bed frame is unfolded.

13. The combination of claim 12, in combination with a tail section leg pivoted to the tail section and extending downwardly therefrom, and means to fold said leg against said tail section upon swinging said tail section upwardly about its pivotal connection to the short fold section.

14. The combination of claim 10, in combination with means to prevent the forward end of the pusher bar sliding in the slot in the short fold section when the short fold section is in a position other than horizontal.

15. In combination, a fixed support adapted to be attached within an upholstered frame, a bed frame comprising a rear head section pivoted at one end to said support, an intermediate section pivoted at its rear end to the forward end of the head section, a short fold section pivoted at its rear end to the forward end of the intermediate section, a front tail section pivoted at its rear end to the front end of the short fold section, said bed frame being adapted to be unfolded to bring said sections into horizontal position, said tail section being foldable upwardly and rearwardly about the forward end of the short tail section from horizontal position to vertical position, substantially at right angles to the short fold section, without moving said head section, intermediate section and short fold section out of horizontal position, said tail section and short fold section being swingable together without relative movement therebetween, and as a unit relative to the intermediate section to incline said short fold section upwardly and forwardly and to incline the tail section rearwardly and upwardly, means controlled by said movement of said short fold section and said tail section to lock said tail section to said fold section in right angle position thereto, and means controlled by said movement of said short fold section and ,tail section as a unit to cause the head section to swing about its pivot to a downwardly and forwardly inclined position, and said intermediate section to an upwardly and forwardly inclined position, said last means including means to prevent movement of said short fold section from horizontal position relative to the intermediate section Without causing movement of the head section relative to the support and relative movement between the head section and intermediate section.
